A flexible panel directly on a roof cannot breath therefor suffers much more than if it were elevated to allow air flow underneath. They do need to dissipate heat to be most effective not to mention they will last a lot longer if not overheated.
This is an excellent point raised by Midnight sun and I should have mentioned it.
This is why I used the elevator bolts. My panels do not rest on the fibreglass, however, I will be putting a spacer in the centre, on the under side of my panels to ensure more air flow.

Ya air flow for cooling is definitely important but you also don't want that sitting directly on the fiberglass because if any sweating goes on or the space under the panels retains rain water you will likely end up with blistering of your gelcoat, pretty common under some things like bow cushions.
